I GEORG HEINZE, OF KLOTZSCI-IE, NEAR DRESDEN, SAXONY, GERMANY.

WATER-VELOCIPEDE.

. SPECIFICATION forming part of Letters Patent No, 413,719, dated October 29,- 1889.

Application filed April .8, 1889- To all whom it may concern.-

Be it known that I, GEORG HEINZE, a subject of the King of Saxony, residing. at Klot'zsche, near Dresden, in the Kingdom of Saxony, Elnpire of Germany, have in vented a certain new and useful Improved Water-Velocipede; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to water-velocipedes, and the object thereof is to construct a suitable velocipede of this nature for sporting purposes, &c.

The improved construction is represented in the annexed sheet of drawings, in which- Figure 1 is a Vertical longitudinal central section, Fig. 2 a plan, and Fig. 3 a cross-section, of the Water-velocipede hereinafter described, and of which the novel features are pointed out in the claim.

The boat or floating structure of the velocipede consists of the two lateral tapered cylinders A A, placed parallel with each other and connected by the shorter portion or dry-well B, sufficient to receive the seat and mechanism and sufficiently large to support passengers or luggage in addition to the operator. Behind the seat-space B are the screw-propeller S and the rudder R. The latter is hinged to a block R on a cross-rod R fixed to the floats A A, and its downwardly-proj ectin g pintle R terminates in a cross-bar WV, the ends of which J of the frictional coupling, by which it is connected with the operating-gear. In the front part of the space B is journaled the crank-shaft D, having fly-Wheels D, and the crank-wrists of which are connected by links D to the ends of two pedal-levers M M, pivoted at a suitable position at their rear ends, and having the foot-rests M M, respectively, so that the operator on seat 0 may alternately depress the said pedal-levers and cause the revolution of the shaft D. The latter carries also the chain-wheel E, connected by chain with the chain-wheel F on the shaft Q. On the shaft Q slides a sleeve carrying the friction-wheels J J, and adapted to be moved by the lever N in the known manner for bringing the one or other wheel J in contact with the wheel J on the propeller-shaft, and consequently causing the revolution of the latter in the one or other direction and forward or backward propulsion of the velocipede. The wheel J is made to slide upon the shaft L, and the collar K on the former engages the lever 0, so that by corresponding movement of the lever O the radial distance of the wheel J from the shaft Q may beenlarged or diminished, and the power and the speed of the vessel be consequently brought under greater command of the operator.

I claim- In water-velocipedes, the combination of two lateral floats A A,a central connecting dry-Well B, a rudder behind the rear of said'
